' SPARE-TIRE CASE.

Specification of Letters Patent.

Patented June 29, 1909.

Application filed January 21, 1909. Serial No. 473,574.

accompanying drawing, is a specification,

like letters on the drawing representing like parts.

This invention has for its object the production-of a novel. form oftire case for envelopingand protecting a spare tire such as used onautomobiles.

The particular obgect is to provide such a case which shall at its lineof closure fit snugly against and cling to the tire so as to prevent asfar as possible .the' entrance of moisture anddust,

- The object is'also to provide a case which will be adiustable to tiresof Varying diameter and varying size.

Hitherto in the construction of .these tire cases the tire case has beencommonly formed (1) of a bead strip fitting the head or base of the tireand cut with straight'parallel edges; (2) of two flange strips coverinthe swelling side portions of the tire and cut with concentric circularedges; and a tread strip covering the tread portion of the tire and likethe bead strip cut with straight parallel edges.

In the present invention I'have discovered that by forming the treadstrip of a circular form that a much better fit can be obtained andfewer fastening devices need be employed.

The main feature of this invention resides, therefore, in providing acircular strip, or a strip having substantially concentric circularedges for the tread portion of the tire. \Vhen the tireis thusconstructed the free edge of the tread strip binds closely against thetire preventing the admission of 'water and dust and holding the tirefirmly in place V without any substantial wrinkling. It enables the tireto be readily placed in position and in practice I have'found threefastening devices, such as snap buttons, located at the peripheral edgeof the tire case amply sufficient to hold the tire case in position, one

being located-at one end and two at the other end.

An additional feature or the invention re-' sides in. providing theoverlapping edges of site side of the tire case.

the case with aplurality of concealed fastening devices enabling thetire case to be adjusted incross-section to provide for the varyingcross-section of tires of thegeneral size due to dllierent styles ofmanufacture. The nature of the invention-will more .fully appear fromthe accompanying description and drawings and will be particularlypointed out in the claims.

the" tire case with the overlying-ends turned back to show theconstruction. [Fig 3 is a cross-section of'the'tire case in theform itassumes when in position.

The tire case is shown as arranged for the usual form of tire'having ahorseshoe-shape in cross-section.

The tire case comprises essentially a bead strip A covering the head orbase of the tire, flange strips B, C united thereto and covering thesides of the tire, and a. tread strip E covering the tire'tread.

The inner surface or bead of the tire being practically cylindrical, thebead strip .A is a straight strip of material having parallel. edges.The sides of the tire being circular the flange strips-B and G are cutfroimmaterial in a circular form. The lower edges of-these strips beingattachedto .the edges of the bead strip A are cut on circles whoseradiiare equal to the radius of the inner surface or head of the tire. Thelength of the radius of the outer edge of these strips should besubstantially equal to the radius of the center line of the tread of'thetire, so as to prevent liability of wrinkling.

The space at the tread-portion of the tire or the space lying betweenthe edges of the side strips B and C is protected by the tread strip E,of a single piece and having its edges substantially circular. Theessential feature of the invention is that the tread strip shallsubstantially cover the treadportion of the tire and that its outer orfree edge shall be formed on a circle having a radius less than theradius of the outer edge of the side strip to which it is connected, andthat its free edge shall overlap the oppo- The reason for this and theresult secured will be apparent. One edge pf'tho tread stripE, forexample,

must be united to the edge of the flange strip B, and must consequentlybe of equal length to the said edge. edge of the tread strip musttherefore be formed on a radius less than the radius of the outer edgeof. the flange strip B, and

' hence the free circular edge of the tread not drive into the case.

strip E will be formed on a radius less than the radius of the outeredge of the strip B by a distance substantially equal to the Width ofthe tread strip. The free edge of the tread strip E will therefore becut on a smaller circle than the'circular line on the side of the tireagainst which it will rest,

and consequently it will cling firmly to and fit snugly against thetire. I find in practice that the fit is so snug and firm at this 'pointthat there is little danger of dust or moisture passing into the tirecase at the edge, andthe edge is located well beneath the bulging sidesof the tire so that rain will The manner in Whichthe tire case clings tothe tire when thus constructed requires the use of but few fasteningdevices and I havefound in practice that three snap buttons were amplysufii- *guished from a straight-edged strip.

In cutting the tire case due allowance must be made for the seams whichare to unite the edges of the strips.

as to bring its edge Well backfrom the swell of the hrs at the sides sothat rain or water Wlll not drive into or drip into this edge at thebottom of the'tire case when supported in a vertical position.

I find that in practice it'is sufficient to place one fastener onthe end of the case which is first fastened around the tire and twofasteners on the end which tells scopes over the said end. The fastenerson the overlying end are'preferably placed one at the end and one ashort distance back from the end and serve to hold the tire firmlywithout wrinkling whatever the circiunfeiential adjustment vby means ofthe fasteners G, H may be.
